Planting and Growing Allium (Ornamental Onion) Plants
Allium (Ornamental Onion) is a large genus of culinary and ornamental plants with deep green folliage and excellent deer and rabbit resistance.
Bulb types are late spring/early summer bloomers that go summer dormant.
Late summer/early fall bloomers (like 'Millennium') are not bulbous and grow actively over the spring and summer months.
Plant in most any type of soil including clay, with full to part sun. Mulch with common mulch materials, such as bark, pine needles or gravel.
Allium prefers dry to moderate soil moisture once established.
Cut bulb-types to ground level when foliage begins to turn yellow in summer. Cut non-bulb types to the ground in fall.
Fertilize lightly in fall with Yum Yum Mix/compost blend.
